 Long Range Directional Acoustic Device For Police Use

1500M Vehicle-mounting Long Range Directional Acoustic Device for security forces

 

A new generation of long range acoustic dispelling device of directional voice transmission can issue extended range of commanding voices, warnings and deterrent tones. It ensures that the broadcasts can be heard clearly in a very long distance, and even cross some buildings. It is featured high direction, high vocal intensity, high clarity, effectively, and ensure vocal effectiveness and accuracy over much extended range. The device can be widely used in communications, commands, dispelling the demonstration, border warning, human search and rescue, maritime smuggling and other fields. The latest version adopts updated driver technology with lower frequency, longer range and more durable.

 

Main Applications:

For anti-drug, anti-smuggling and anti-cross border at the frontiers, anti-smuggling at sea, public security and law enforcement, broadcasts and dispersion at airports and sea ports etc.

1. Issue prompt notifications and warnings to the people, vehicles in some far distance

2. Issue warnings for emergencies (illegal rallies, riots, unprovoked approach and invasion)

3. Issue unbearable noises to the illegal invasion ships at the territorial waters

4. To control the judicial detainees and prisoners, and to patrol

5. For communication and coordination at the site of severe natural disaster rescue

6. To prevent terrorists, hostages and organized terrorist activities

7. To prevent illegal entry or smuggling across borders

Key Technologies:

1. Energy transducer array: adopt the advanced technologies of finite element method, electromechanical coupling analysis, solid-fluid coupling analysis, build 2D mathematical model of coherent superposition,  use nonlinear neural network compensation control, effectively forming the sound wave bunching angle, to achieve the best focus, orientation and penetration effect;

2. Energy transducer unit: use such new materials as piezoelectric elastic materials, NdFeB, and bending structure to achieve high sensitivity, good impact resistance, and vocal clarity;

3. Ultrasonic modulation: in contrast to the traditional loudspeakers using cylinder mechanism to stimulate air vibration, the directional acoustic device adopts ultrasonic sensor to produce highly oriented ultrasonic signal, which is demodulated to get high directional audible sound by the nonlinear effect of ultrasonic wave in the air.

4. Digital power amplifier: energy-efficient, compact and lightweight, reliable and durable;

5. Low power requirement

6. System integration: effective coupling between various levels of the system, effective impedance matching between the amplifier and transducer, dynamic range adjustment of digital signal processing and digital power amplifier, distortion correction etc.
